you can start looking.. but don't hold your breath.
the front bracket is probably the most rare.. but also the easiest to make correctly.
the tranny or hip bracket is hardest to make.. but a lil more common.
as said. the 1-arm laoder came in a short and long box version. long box for the 48-64 models.. and short box for the 65+
i've attached 3 pics.
1 shows the regular ag chassie bracket set. the hip bracket will work on the rowcrop
next pic is similar to kirks extende dhip bracket for a short box. 3rd pic shows my 951 witht he front hanger bracket.. and my big 3/4" ratched hanging off a bolt on the hip bracket.
now.. with a rowcrop you have the unique opportunity to build the hip bracket and make it work. on an ag chassis there is a steering arm on the left side int he way and it's hard to scab one up. with a rowcrop and no steering arm onthe left. you CAN make up a good strong repop hip bracket and be fine.
